The Trimble Slate Controller doesn’t have screen snap or print screen option. However, there is a small utility called MyMobiler (http://mymobiler.com/windowsmobile.html) which can be installed on the Slate and a PC. Then, connect the Slate via USB cable to the PC and you can bring the Slate screen on the PC via MyMobiler, afterwards, take screen snaps and control the slate using the mouse.
